Does light-speed fire control leave time to evade?

Even directed-energy defenses face engagement geometry: at extreme light-second ranges, fire-control information and the beam itself cannot arrive instantaneously.

Question

Do light-speed limits on point-defense fire control give an incoming missile time to dodge at long range?

Short answer

Yes. At ranges measured in many light-seconds, the delay gives a maneuvering missile an opportunity to evade.

Notes

Light-speed weapons do not remove time-of-flight and information delays. At a range of about 75 light-seconds, a point-defense laser and the targeting information that guides it cannot affect the missile immediately. A missile that continues to maneuver during that interval may move away from the predicted intercept point. Long range therefore creates an evasion opportunity even for a beam weapon.
